Description

Technical Field

[0001] This invention relates to the field of cutting machinery structures, and in particular to a guide wheel structure and a wire saw using the guide wheel structure. Background Technology

[0002] In the field of wire saw cutting, the guide wheel structure is one of the core components of a wire saw machine. It is mainly used for limiting, guiding, and adjusting the angle of the high-speed wire saw to ensure that the wire saw can accurately cut the workpiece. Existing guide wheel structures generally include a housing, transmission components, and a cylindrical component for threading the wire saw. These components are assembled into a single unit using appropriate assembly methods, providing support and guidance for the wire saw and meeting the needs of conventional cutting operations.

[0003] In the existing technology, when assembling or disassembling wire saws, the guide wheel structure usually requires the core transmission components, such as the transmission body, to be disassembled and separated in order to provide the necessary operating conditions for the wire saw to be inserted or removed. This operating mode not only increases the operation process of equipment maintenance, but also easily damages the assembly accuracy between components due to repeated disassembly of core components, which in turn has an adverse effect on the subsequent operational stability and guiding accuracy of the guide wheel structure. Summary of the Invention

[0004] To address the shortcomings mentioned above in the background art, the present invention provides a guide wheel structure and a wire saw using the guide wheel structure.

[0005] The present invention adopts the following technical solution: In a first aspect, the present invention discloses a guide wheel structure, the guide wheel structure comprising: The housing has a through mounting hole and a clearance opening on one side, which extends through the mounting hole. A fixed cylinder, wherein a first notch is provided on one side of the fixed cylinder along its axial direction, the fixed cylinder passes through the mounting hole, and the first notch corresponds to the clearance opening; A packaging tube is provided with a second notch on one side of the axial direction. The packaging tube passes through the interior of the fixed tube and is detachably fixed relative to the fixed tube. After the packaging tube is fixed, the second notch and the first notch are misaligned. A transmission body, wherein a third notch is provided on one side of the transmission body along the axial direction, the transmission body is located inside the outer shell, and the transmission body is coaxially sleeved and rotated outside the encapsulation cylinder; Mounting plate, the mounting plate is fixed to one end of the transmission body, and the mounting plate is connected to a guide wheel, the guide wheel is restricted to rotate on the side of the mounting plate facing the encapsulation cylinder, and the axis of rotation of the guide wheel is perpendicular to the axis of rotation of the encapsulation cylinder; When the second notch and the third notch both correspond to the first notch, a channel is formed for the wire saw to pass through the clearance opening into the encapsulation cylinder or to move out of the encapsulation cylinder.

[0006] In a possible implementation of the first aspect, the transmission body includes a support ring, the mounting plate is fixed to the transmission body, and a plurality of support wheels are distributed circumferentially around the center of the mounting hole inside the housing. The annular surface of the support wheel is concave to form an embedding groove, and the annular surface of the support ring is adapted to be embedded in the embedding groove of each of the support wheels.

[0007] In one possible implementation of the first aspect, the guide wheel structure further includes an adjusting motor fixed to the outside of the housing, the output shaft of the adjusting motor extending into the housing to fix a drive gear, the transmission body further including a transmission gear fixed between the support ring and the mounting plate, the transmission gear and the support ring being coaxially corresponding, and the transmission gear meshing with the drive gear.

[0008] In one possible implementation of the first aspect, the guide wheel structure further includes a shielding body, which includes a fixing ring, a connecting ring, and a shielding ring. The two ends of the connecting ring are respectively fixed to the shielding ring and the fixing ring, and the fixing ring and the shielding ring are parallel to each other. The fixing ring is fixed to one end of the transmission body connected to the mounting plate, so that the connecting ring is located inside the clearance opening, and the shielding ring is located outside the housing to shield the gap between the transmission body and the clearance opening.

[0009] In a possible implementation of the first aspect, the housing is fixed to the connecting shaft at the position where the support wheel is located, the support wheel has an embedded bearing, and the bearing is sleeved on the connecting shaft.

[0010] In one possible implementation of the first aspect, the guide wheel structure further includes an adjustment assembly. The housing is configured with the adjustment assembly at the location where each of the connecting shafts is located. The adjustment assembly includes a limiting pin and an adjustment block. The housing is provided with a first strip hole at the location where the connecting shaft is located. The extension line of the length direction of the first strip hole is aligned with the radius line of the mounting hole. The end of the connecting shaft away from the support wheel passes through the first strip hole and is connected and fixed to the middle of the adjustment block. Strip holes are provided on both sides of the adjustment block. The limiting pin is embedded in both strip holes. The stud of the limiting pin passes through the strip hole and is threadedly connected to the housing to fasten the adjustment block to the housing.

[0011] In a possible implementation of the first aspect, an upper sealing plate is fixed on the top of the housing at the position of the clearance opening, the upper sealing plate sealing the upper opening of the clearance opening, and a side sealing plate is fixed on the side of the housing, the side sealing plate being L-shaped, and the side sealing plate sealing the side opening of the clearance opening and the opening on the opposite side of the upper sealing plate.

[0012] Secondly, the present invention also discloses a wire saw using the above-described guide wheel structure, the wire saw comprising: A conveying platform, wherein the conveying surface of the conveying platform forms a strip-shaped sawing gap, which is perpendicular to the conveying direction of the conveying platform; A sawing frame, which is a C-shaped frame, with the opening side of the sawing frame facing the conveying platform. Several guide wheels are arranged inside the sawing frame, and a wire saw is wound around each guide wheel so that the wire saw forms a vertical cutting segment at the opening of the sawing frame. A moving device is disposed on one side of the conveying platform, and the moving device drives the cutting segment of the sawing frame to move relative to the sawing gap; The guide wheel structure is located above the opening of the sawing frame, and the outer shell is fixed to the sawing frame. When the cutting section of the running wire saw enters the sawing gap, the transmission body rotates, driving the guide wheel to rotate and adjust the cutting angle of the wire saw.

[0013] In a possible implementation of the second aspect, the conveying platform includes two conveyors, each conveyor including a frame, rollers, a conveyor belt and a drive motor. A row of rollers is distributed above the frame, and the drive motor drives the rollers at the ends of the frame to rotate. The conveyor belt is wrapped around the rollers on the frame, and the upper surface of the conveyor belt forms the conveying surface. The gap between the conveyor belts of the two conveyors forms the sawing gap.

[0014] In a possible implementation of the second aspect, the conveyor further includes a tensioning assembly comprising a base, an adjusting seat, an adjusting roller, and an adjusting bolt. The base, the adjusting seat, and the adjusting bolt are provided on both sides of the frame. The base is fixed to the frame, and a limiting member is fixed to the lower end of the base. The adjusting seat is restricted to vertical movement relative to the base. A nut is fixed to the adjusting seat. The adjusting bolt passes through the limiting member with clearance fit and is threadedly connected to the nut. The axial direction of the adjusting bolt is restricted to be fixed relative to the limiting member.

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: when the second notch of the encapsulation tube and the third notch of the transmission body are rotated to correspond with the first notch of the fixed tube, a through channel can be directly formed for the wire saw to pass through the clearance port into the encapsulation tube or move out of the encapsulation tube. The operator does not need to disassemble or dismantle the core transmission components such as the transmission body. By simply rotating the encapsulation tube and the transmission body to align the notches, the assembly and disassembly of the wire saw can be completed quickly. This avoids problems such as decreased assembly accuracy and increased wear of components caused by disassembling the transmission components. It effectively reduces the operation steps in the equipment maintenance process, reduces the workload of the operators, and shortens the maintenance downtime of the equipment. Its technical effect is to realize the convenient and non-destructive loading and unloading of the wire saw. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings.

[0035] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0036] Furthermore, in this embodiment, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used to describe and clarify relative positions, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0037] This invention provides a guide wheel structure and a wire saw using the guide wheel structure, as shown in the attached figure. Figures 1 to 4 As shown, the guide wheel structure includes a housing 1, a fixing cylinder 2, an encapsulation cylinder 3, a transmission body 4, and a mounting plate 5. See also the attached diagram. Figure 7The outer casing 1 has a through mounting hole 101, and a clearance opening 102 is provided on one side of the outer casing 1, extending through the mounting hole 101. A fixed cylinder 2 is inserted into the mounting hole 101, and a sealing cylinder 3 is inserted into the fixed cylinder 2. A transmission body 4 is assembled inside the cavity of the outer casing 1, and the transmission body 4 is coaxially fitted around the sealing cylinder 3 for rotation. A mounting plate 5 is fixed to one end of the transmission body 4, and the mounting plate 5 is connected to a guide wheel 51, restricting the rotation of the guide wheel 51 to the side of the mounting plate 5 facing the sealing cylinder 3, and the axis of rotation of the guide wheel 51 is perpendicular to the axis of rotation of the sealing cylinder 3.

[0038] As attached Figure 8 As shown, a first notch 201 is provided on one side of the axial direction of the fixed cylinder 2. After the fixed cylinder 2 passes through the mounting hole 101, it is connected and fixed to the outer shell 1. The first notch 201 corresponds to the clearance opening 102. In this embodiment, the fixing can be achieved by connecting with through bolts. A second notch 301 is provided on one side of the axial direction of the encapsulation cylinder 3. After the encapsulation cylinder 3 passes through the inside of the fixed cylinder 2, it is detachably connected and fixed to the fixed cylinder 2 by through bolts. After the encapsulation cylinder 3 is fixed, the second notch 301 and the first notch 201 are staggered. Through the staggered arrangement of the second notch 301 and the first notch 201 after the encapsulation cylinder 3 is assembled with the fixed cylinder 2, the sealing performance of the path traversed by the wire saw 82 relative to the inside of the cavity of the outer shell 1 is effectively guaranteed. It reliably prevents impurities such as mud and water from entering the cavity through the inside of the encapsulation cylinder 3, avoiding impurities from interfering with the operation of the transmission components inside the outer shell 1, thereby improving the operating stability and service life of the guide wheel structure.

[0039] Continue to refer to the appendix Figure 8 The transmission body 4 includes a support ring 41 and a transmission gear 42 fixed coaxially. A third notch 401 is provided on one side of both the support ring 41 and the transmission gear 42, and the third notch 401 of the support ring 41 and the third notch 401 of the transmission gear 42 are aligned, forming a structure in which a third notch 401 is provided on one side of the transmission body 4 along its axial direction. (See attached diagram.) Figure 6 The mounting plate 5 is fixed to the part of the transmission gear 42 where the third notch 401 is not provided.

[0040] As attached Figure 9 and 10 As shown, multiple support wheels 45 are arranged in a ring array around the center of the mounting hole 101 inside the outer casing 1. The annular surface of the support wheel 45 is concave to form an embedding groove. The annular surface of the supporting ring 41 is adapted to the embedding groove of each support wheel 45 and is embedded in the embedding groove. Through this assembly structure, the transmission body 4 can be limited within the cavity of the outer casing 1, so that the transmission body 4 can only rotate relative to the outer casing 1, effectively ensuring the coaxiality and stability of the transmission body 4 during rotation and avoiding offset and wobbling. (See attached diagram.) Figure 2 and 4An adjustment motor 43 is fixed to the outside of the housing 1. The output shaft of the adjustment motor 43 extends into the cavity of the housing 1 and is fixedly connected to a drive gear 44. The drive gear 44 meshes with the transmission gear 42. Through the meshing of the drive gear 44 and the transmission gear 42, the adjustment motor 43 can drive the transmission body 4 to rotate, thereby driving the mounting plate 5 and the guide wheel 51 to rotate synchronously.

[0041] Continue to refer to the appendix Figure 2 and 4 The support wheel 45 can be restricted to rotate within the cavity of the housing 1 by the limiting assembly of the connecting shaft 46. Specifically, the assembly method is as follows: the housing 1 fixes the connecting shaft 46 at the position where the support wheel 45 is set, the support wheel 45 is embedded with a bearing 451, the bearing 451 is sleeved on the outside of the connecting shaft 46 in an interference fit, and the connecting shaft 46 and the bearing 451 are axially fixed by a snap ring. The above-mentioned assembly structure of the interference fit of the bearing 451 and the axial fixation of the snap ring can ensure that the support wheel 45 can only rotate relative to the connecting shaft 46, effectively ensuring the stability of the support wheel 45 during rotation and avoiding axial movement. Furthermore, the housing 1 is equipped with adjustment components 47 at the locations where each connecting shaft 46 is set. The adjustment components 47 include limit pins 471 and adjustment blocks 472. The housing 1 is provided with a first strip hole 103 at the location where each connecting shaft 46 is set. The extension line of the first strip hole 103 in the length direction is aligned with the radius line of the mounting hole 101. The end of the connecting shaft 46 away from the support wheel 45 passes through the first strip hole 103 and is connected and fixed in the middle of the adjustment block 472. The adjustment block 472 is provided with a second strip hole on both sides. The limit pins 471 are embedded in both second strip holes. The studs of the limit pins 471 pass through the second strip holes and are threadedly connected to the housing 1. By tightening the limit pins 471, the adjustment block 472 can be fastened to the housing 1. After the support wheel 45 and the support ring 41 wear out due to long-term use, the fastening restriction on the adjusting block 472 can be released by loosening the limiting pin 471. At this time, moving the adjusting block 472 will drive the connecting shaft 46 and the support wheel 45 to move synchronously, so that the embedded groove of the support wheel 45 can continue to be firmly locked on the outside of the support ring 41. Through this adjustable structural design, the wear gap between the support wheel 45 and the support ring 41 can be compensated. The fit and assembly state of the two can be restored without directly replacing the worn parts, thereby effectively extending the service life of the support wheel 45 and the support ring 41 and reducing the maintenance cost of the equipment.

[0042] When assembling or disassembling the wire saw 82, first disassemble the encapsulation cylinder 3 and rotate it until the second notch 301 aligns with the first notch 201. Then rotate the transmission body 4 until the third notch 401 aligns with the first notch 201. At this point, the first notch 201, the second notch 301, and the third notch 401 all align with the clearance port 102, thus forming a through channel for the wire saw 82 to pass through the clearance port 102 into or out of the encapsulation cylinder 3. The operator can use this through channel to insert the wire saw 82 into the encapsulation cylinder 3 through the clearance port 102 to complete the assembly operation, or to remove the wire saw 82 from the encapsulation cylinder 3 through the clearance port 102 to complete the disassembly operation. The entire assembly and disassembly process does not require disassembly of any component of the transmission body 4, which can greatly simplify the assembly and disassembly process of the wire saw 82, improve the maintenance efficiency of the equipment, and reduce the workload of the operators.

[0043] In addition, see attached Figure 1 , 6 As shown in Figure 7, an upper sealing plate 11 is fixed at the position of the clearance opening 102 on the top of the outer casing 1. The upper sealing plate 11 seals the upper opening of the clearance opening 102. A side sealing plate 12 is fixed on the side of the outer casing 1. The side sealing plate 12 is L-shaped and seals the side opening of the clearance opening 102 and the opening on the other side of the clearance opening 102 opposite to the upper sealing plate 11. The combination of the upper sealing plate 11 and the side sealing plate 12 forms a comprehensive sealing structure for the clearance opening 102, which can effectively prevent mud and water generated during the wire saw 82 cutting operation from entering the cavity of the outer casing 1. This prevents mud and water from corroding or interfering with the connection and mating structure of components such as the transmission body 4, support wheel 45, and drive gear 44 inside the cavity, ensuring that each transmission component always maintains a stable and reliable operating state, and further improving the durability and operational stability of the guide wheel structure.

[0044] Please refer to the appendix. Figure 5 , 6In addition to 11, the guide wheel structure also includes a shielding body 6, which includes a fixing ring 61, a connecting ring 62, and a shielding ring 63. The two ends of the connecting ring 62 are respectively fixed to the shielding ring 63 and the fixing ring 61, and the fixing ring 61 and the shielding ring 63 are parallel to each other. The fixing ring 61 is fixed to one end of the transmission body 4 connected to the mounting plate 5, so that the connecting ring 62 is inside the relief opening 102. The shielding ring 63 is outside the outer shell 1 and forms a shield between the transmission body 4 and the relief opening 102, effectively preventing mud and water generated during the wire saw 82 cutting operation from entering the cavity of the outer shell 1 through the gap between the transmission body 4 and the relief opening 102, preventing mud and water from eroding or interfering with the connection and mating structure of each transmission component in the cavity, further improving the overall sealing and protection performance of the guide wheel structure, and ensuring the long-term stable operation of the internal components. In addition, the position of the shield 6 corresponding to the clearance opening 102 is a detachable separation part 64. This separation part 64 is also fixed to the transmission body by means of through bolts. When assembling or disassembling the wire saw 82, the separation part 64 can be disassembled to open the above-mentioned through passage.

[0045] This invention also discloses a wire saw using the above-described guide wheel structure, as shown in the attached figure. Figure 12 As shown, the wire saw includes a conveying platform 7, a sawing frame 8, and a moving device 9. The conveying surface of the conveying platform 7 forms a strip-shaped sawing gap 701, which is perpendicular to the conveying direction of the conveying platform 7. (See attached diagram.) Figure 13 and 14 The conveying platform 7 includes two conveyors, each comprising a frame 71, rollers 72, a conveyor belt 73, and a drive motor 74. A row of rollers 72 is distributed above the frame 71, and the conveyor belt 73 is wound around the rollers 72 on the frame 71, forming the conveying surface on its upper surface. The gap between the conveyor belts 73 of the two conveyors forms a sawing gap 701. The drive motor 74 is fixed to one side of the frame 71, and its output shaft drives the rollers 72 at the end of the frame 71 to rotate, thereby driving the conveyor belt 73 to run smoothly. This causes the raw material placed on the conveyor belt 73 to move relative to the sawing gap 701, providing a stable and continuous feed for subsequent sawing operations and ensuring that the raw material can be cut along a preset path through the sawing gap 701.

[0046] Furthermore, the conveyor also includes a tensioning assembly, such as the attached... Figure 15As shown, the tensioning assembly includes a base 751, an adjusting seat 752, an adjusting roller 753, and an adjusting bolt 754. The base 751, adjusting seat 752, and adjusting bolt 754 are provided on both sides of the frame 71. The base 751 is fixed to the inner side of the frame 71, and a limiting member 755 is fixed to the lower end of the base 751. The adjusting seat 752 is restricted to vertical movement relative to the base 751. This restriction can be achieved by providing limiting grooves on both sides of the base 751 laterally, with the two sides of the adjusting seat 752 fitting into the two limiting grooves with a clearance fit, thereby restricting the adjusting seat 752 to vertical movement only along the limiting grooves. The two ends of the adjusting roller 753 are respectively connected to the adjusting seats 752 on both sides of the frame 71, and the conveyor belt 73 passes under the adjusting roller 753. The adjusting seat 752 fixes the nut 756, and the adjusting bolt 754 passes through the limiting member 755 with clearance fit and is threadedly connected to the nut 756. The axial direction of the adjusting bolt 754 is restricted to be fixed relative to the limiting member 755.

[0047] When the tension of the conveyor belt 73 needs to be adjusted, rotating the adjusting bolt 754 will move the adjusting seat 752 along the limiting groove, thereby causing the adjusting roller 753 to rise and fall synchronously. In specific operation, when the adjusting roller 753 descends, it will pull the conveyor belt 73 downward to tighten it, which can effectively prevent the conveyor belt 73 from slipping during operation and ensure that the raw material placed on the conveyor belt 73 can maintain a stable conveying posture. It can effectively prevent the raw material from shifting or moving during the conveying process and ensure that the raw material is smoothly conveyed to the sawing gap 701 for cutting. When the adjusting roller 753 rises, it will loosen the conveyor belt 73, which is convenient for inspection and maintenance of the conveyor belt 73. At the same time, it can also prevent the conveyor belt 73 from being in a tense state for a long time, which will cause fatigue damage and effectively extend the service life of the conveyor belt 73.

[0048] Please refer to the appendix. Figure 16 and 17 As shown, the sawing frame 8 is a C-shaped frame, with its opening facing the conveying platform 7. Several guide rollers 81 are arranged inside the sawing frame 8, and the wire saw 82 is wound around each guide roller 81, forming a vertical cutting section 821 at the opening of the sawing frame 8. The outer shell 1 of the guide roller structure is fixedly connected above the opening of the sawing frame 8, and the guide roller 51 abuts against one side of the cutting section 821 of the wire saw 82. This provides reliable limiting and guiding for the high-speed running wire saw 82 cutting section 821, effectively preventing the wire saw 82 from shifting or vibrating during the cutting operation, ensuring that the cutting section 821 corresponds to the sawing gap 701 of the conveying platform 7, thereby improving the cutting accuracy and operational stability of the wire saw machine on the raw material.

[0049] Continue to refer to the appendix Figure 12 The moving device 9 is located on one side of the conveying platform 7, and the moving device 9 drives the cutting section 821 of the sawing frame 8 to move relative to the sawing gap 701, as detailed in the attached figure. Figure 18 As shown, the moving device 9 includes a base 91, a moving seat 92, a lead screw 93, and a moving motor 94. The base 91 is fixed to one side of the conveying platform 7. The lead screw 93 is mounted on the base 91 and rotates. The moving motor 94 is fixed outside the base 91 and drives the lead screw 93 to rotate. The moving seat 92 is connected to the base 91 and slides relative to the conveying platform 7. The bottom surface of the moving seat 92 and the lead screw 93 are spirally connected. The sawing frame 8 is fixed on the moving seat 92. By driving the lead screw 93 to rotate through the moving motor 94, the moving seat 92 and the sawing frame 8 can be driven to slide smoothly along the base 91. This, in turn, drives the cutting section 821 of the wire saw 82 to move relative to the sawing gap 701. This allows for flexible adjustment of the relative position of the cutting section 821 and the sawing gap 701, adapting to the cutting and processing needs of different specifications of raw materials. At the same time, the spiral drive of the lead screw 93 has the characteristics of high transmission accuracy and good running stability, which can effectively ensure the positional accuracy of the cutting section 821 during movement, thereby improving the cutting quality and operating efficiency of the wire saw.

[0050] During operation, the encapsulation cylinder 3 is first disassembled and rotated until the second notch 301 aligns with the first notch 201. Then, the transmission body 4 is rotated until the third notch 401 aligns with the first notch 201. At this point, the first notch 201, the second notch 301, and the third notch 401 all align with the clearance port 102 to form a through channel. The operator can insert the wire saw 82 into the encapsulation cylinder 3 through the clearance port 102. After the wire saw 82 is inserted, the encapsulation cylinder 3 is reset and securely connected to the fixing cylinder 2, so that the second notch 301 and the first notch 201 are staggered to ensure the sealing performance of the cavity inside the outer shell 1. Then, the wire saw machine is started. The conveyor belt 73 of the conveying platform 7 moves the raw material toward the sawing gap 701. The moving device 9 operates synchronously, driving the lead screw 93 to rotate through the moving motor 94, which in turn drives the moving seat 92 and the sawing frame 8 to slide, so that the cutting section 821 of the wire saw 82 is aligned with the sawing gap 701. When the cutting section 821 of the running wire saw 82 enters the sawing gap 701 and comes into contact with the raw material, the regulating motor 43 starts and drives the transmission body 4 to rotate through the meshing of the drive gear 44 and the transmission gear 42. During the rotation of the transmission body 4, the mounting plate 5 and the guide wheel 51 rotate synchronously. The guide wheel 51 abuts against one side of the cutting section 821 of the wire saw 82 and adjusts the cutting angle of the wire saw 82 by its own rotation, so as to adapt to the cutting needs of different positions of the raw material and improve the flexibility and accuracy of the cutting operation.

[0051] In summary, the guide wheel structure disclosed in this invention forms a mating structure in which the notches of each component can correspond or be misaligned through the coaxial nesting assembly of components such as the outer shell 1, the fixed cylinder 2, the encapsulation cylinder 3, and the transmission body 4. When the second notch 301 of the encapsulation cylinder 3 and the third notch 401 of the transmission body 4 correspond to the first notch 201 of the fixed cylinder 2, a channel can be formed for the wire saw 82 to pass through the clearance port 102 into the encapsulation cylinder 3 or to move out of the encapsulation cylinder 3. This allows for convenient installation and removal of the wire saw 82 without disassembling the transmission gear 42. At the same time, the misaligned mating of the notches of each component ensures the sealing performance of the cavity of the outer shell 1. Combined with the protective structure of the shield 6, the upper sealing plate 11, and the side sealing plate 12, it can effectively prevent mud and water from seeping into the cavity and avoid corrosion of the internal transmission components. The wire saw machine of this invention, which uses the guide wheel structure, transports raw material through the conveying platform 7. The wire saw 82 forms a vertical cutting section 821 through the guide wheel 81 of the sawing frame 8.
